FB P905 dual extruder, 3 sides cooling

thingiverse

For dual extruders, It's remix of existing system features a holder for turbo fan with extended screws hole. The down part is divided into two sections, allowing the cooling system to be printed with two different filaments, such as PLA and ABS or PLA and HIPS. The direction of cooling can be adjusted in the future; however, it has not been tested yet. Rotate it before printing! 27.11.2018 update: I have identified 2 mistakes. Firstly, the brim details for glue do not function perfectly, but this is not a critical issue. Secondly, air holes in the cycle require small holes to be drilled downward to change the airflow direction; I corrected this by using a knife. I plan to modify the model but will not do so at this time. 30.11.2018 update: The flow within the cycle has been improved, and strong "hands" have been added. The left and right screw nuts have also been reduced in size. To print this design, it is sufficient to download and print files with a "New" appendix, 3.stl, and 4.stl.
